Anatomical Area

La fosa infratemporal es un área anatómica clínicamente importante para la administración de agentes anestésicos locales en odontología y cirugía maxilofacial. Fueron estudiadas variaciones en la anatomía del nervio alveolar inferior y la arteria maxilar en la disección infratemporal. Durante la disección rutinaria de la cabeza en el cadáver de un varón adulto, fue observada una variación excepcional en el origen del nervio alveolar inferior y su relación con las estructuras circundantes. El nervio alveolar inferior se originaba en el nervio mandibular por dos raíces y la primera parte de la arteria maxilar estaba incorporada entre ambas. El origen embriológico de esta variación y sus implicaciones clínicas es debatido. Dado que la arteria maxilar transcurría entre las dos raíces del nervio alveolar inferior, y el nervio estaba fijado entre el foramen oval y el foramen mandibular, el atrapamiento vásculo-nervioso pudo causar entume-cimiento o dolor de cabeza e interferir con la inyección de anestésicos locales en la fosa infratemporal.  Variaciones anatómicas en esta región deben ser tenidas en cuenta, especialmente en casos de tratamiento fallido de neuralgia del trigémino. Infratemporal fossa is clinically important anatomical area for the delivery of local anesthetic agents in dentistry and maxillofacial surgery. Variations in the anatomy of the inferior alveolar nerve and maxillary artery were studied in infratemporal dissection. During routine dissection of the head in an adult male cadaver an unusual variation in the origin of the inferior alveolar nerve and its relationship with the surrounding structures was observed. The inferior alveolar nerve originated from the mandibular nerve by two roots and the first part of the maxillary artery was incorporated between them. An embryologic origin of this variation and its clinical implications is discussed. Because the maxillary artery runs between the two roots of the inferior alveolar nerve, and the nerve was fixed between the foramen ovale and mandibular foramen, neurovascular entrapment may cause pain numbness or headache and may interfere with the injection of local anesthetics into the infratemporal fossa. Anatomical variations in this region should be kept in mind, particularly in cases of failed treatment of trigeminal neuralgia.

In occlusive vascular brain diseases, the structure of the circle of Willis is of immense importance. A high percentage of variations have been reported in the arteries forming circle of Willis. These have profound clinical implications. With advances in interventional radiological procedures, the interventional radiologists and neurosurgeons need to have thorough knowledge of these variations. This article will help readers understand the significance of anatomical variations and their clinical effects.

Careful Observation

Background. Descriptive evaluation of nerve variations plays a pivotal role in the usefulness of clinical or surgical practice, as an anatomical variation often sets a risk of nerve palsy syndrome. Ulnar nerve (UN) is one amongst the major nerves involved in neuropathy. In the present anatomical study, variations related to ulnar nerve have been identified and its potential clinical implications discussed. Materials and Method. We examined 50 upper limb dissected specimens for possible ulnar nerve variations. Careful observation for any aberrant formation and/or communication in relation to UN has been carried out. Results. Four out of 50 limbs (8%) presented with variations related to ulnar nerve. Amongst them, in two cases abnormal communication with neighboring nerve was identified and variation in the formation of UN was noted in remaining two limbs. Conclusion. An unusual relation of UN with its neighboring nerves, thus muscles, and its aberrant formation might jeopardize the normal sensori-motor behavior. Knowledge about anatomical variations of the UN is therefore important for the clinicians in understanding the severity of ulnar nerve neuropathy related complications.

Functional Neck Dissection

Prevention of the spinal accessory nerve (SAN) is an indispensable aspect of the functional neck dissection surgery to avoid highly disabling shoulder syndrome postoperatively. This requires comprehensive knowledge of the anatomy of SAN and its variations. Rare anatomical variations like SAN duplication can result in an inadvertant injury to the SAN. We report a case of duplication of SAN, which was encountered while doing a functional neck dissection surgery for oral squamous cell carcinoma. No iatrogenic injury occurred during the surgery and neither there was any SAN dysfunction post-operatively. Meticulous dissection and consistent identification of SAN, along with vast anatomical knowledge is the key to the preservation of the nerve during the surgery. This report aims to broaden our anatomical knowledge of SAN and also discuss the clinical implications and literature pertaining to the duplication of SAN.

AbstractMany authors have reported and classified several anatomical variations between the musculocutaneous (Mc) and median (Me) nerves, regarding their origin, number, and proximity with the coracobrachialis muscle. There also are, in the scientific community, records classifying the origin of supernumerary heads of the biceps brachii muscle. However, the occurrence of both aforementioned variations in the same arm is very uncommon. During a routine dissection of the right upper limb of a male cadaver, a third head of the biceps brachii was found originating from the fibers of the brachialis muscle, as well as a communicating branch between the Mc and the Me nerves, in the same limb. The objective of the present case report is to describe these multiple variations found, relating them and discussing their relevant clinical implications.
